LAN D-MARKER.

SPECIFICA'IIION forming part of Let-ters Patent No. 543,877, datedAugust 6, 1.895.

Ipplication filed May 13, 1895. Serial No. 549,144. (No model.)

T LLZZ whom, iv' may concern:

Be itknown that I, WILLIAM M. LEwIs, a citizen of the United States,residing at Walnut, in the county of Marshall and State of Indiana, haveinvented certain new and usefulV Improvements in Land-Markers for CornPlanters; and I do hereby declare the following to bea f ull, clear, andexact description of the invention, such as will enable others roskilled in the art to which it appertains to make and use the same.

My invention has reference to improvements in land-markers forcorn-planters, and seeks to so improve the construction of the I5 markeras to enable it to yield to and pass over obstructions and also tosimplify the construction of the parts which support and reverse themarker. These objects Ivattain by the useof the device illustrated inthe accomzo panying drawings; and the invention consists in certainnovel features of the same, as will be hereinafter described andclaimed.

In the drawings referred to above, Figure l is a plan view of myimproved marker and so much of the corn-planter frame as is necessary toa proper understanding of the invention, and Fig. 2 is a rear elevationof the'sarne.

The planter-frame A consists ot longitudinal and transverse beams orsills B and forms 3o no part of my present invention. In the reartransverse beams of the frame I journal a rock-shaftA C, the rearextremity of which is forked, as at D, and has pivoted thereto the endof the marker E. The marker is con- 3 5 structedin two sections F G,which are joined by the coupling-plates H, vsaid plates being rigidlysecured to the upper land lower sides of the inner member ofthe markerandvhaving the outer member or section pivoted be- 4o tween their outerends. The inner end of the outer section extends inward beyond the pivotI, and a frangible pin orv key J is inserted through said inner end andthe connecting-` plates. Journaled in suitable bearings upon the frameand near the sides thereof are the longitudinally-disposed rock-shaftsK, havingr their front ends provided with the foot-levers L, projectinginward toward the medial line of the frame, and their outer endsprovided with the outwardly-projecting marker-supporting arms M, asclearly shown. The extremities of these marker-supporting arms areformed into or provided with the lateral rests N, which receive themarker and are provided with the vertical prongs or stops to guide themarker into proper position and prevent too great play of the same. Themarkersupport ing arms are held up in their proper positions by springsO, which are secured to the rear end of the frame and project` laterallyoutward and bear against the under sides of the said arms at the ends ofthe same.

The machine' is drawn over` the ground in the usual manner, and themarker operates as usual. When the end of the line has been reached, thefoot-lever is depressed, so as to raise the marker sufficiently topermit the machine to be turned. Thedriver then may dismount and reversethe marker, or he may reverse it by giving the foot-lever a sharpdownward thrust, thereby throwing the markerv over to the opposite sideof the machine.

'Should the marker strike a stone or other unyielding obstruction, itwill swing slightly backward until arrested by the rear prong, and thecontinued travel of the planter will then cause the frangible pin tobreak, so that the outer member or section willswing around theobstruction. A new pin may be quickly inserted and the planter thendriven on over the field. y

It will be seen that I have provided a very simple marker, which can bequickly and easily reversed and which will readily pass overobstructions.

Having-thus described my invention, what I claim, and desire to secureby Letters Pat ent, is'

The combination with acorn planter frame, of a land marker attachment,consisting essentially of a marker arm E pivoted to the rear of theframe and adapted to swing vertically from one side to the other, a pairof rock shafts K extending longitudinally of the frame, one of saidshafts being journaled on each side of the pivot of said marker arm-andeach rock shaft being provided at its forward end with an inwardlyturned foot lever and at its outer end with an outwardly turned Intestimony whereof I ax my signature marker-supporting arm provided witha lat in presence of two witnesses. eral rest for1 the marker arm, andsprings secured tothe frame and bearing on the un u WILLIAM M. LEWIS.del` side of the marker-supporting arm and Witnesses: adapted toresiliently support the same, sub- J. L. MCCOY,

stantially as described. E. M. MCCOY.
